+The additional ``h``, ``r``, ``b``, and ``l`` specifiers are used to specify
+host, reversed, big or little endian order data respectively. Host endian
+order means the data is interpreted as a 32-bit integer and the most

+matches the byte order stored in memory on big-endian systems, and is reversed
+on little-endian systems.

+  the cluster management register block. This binding uses the standard
